Microbial fuel cells (MFCs) are a newly developed bio-electrochemical technology. MFCs provide new opportunities for energy generation through conversion of organic matter to electricity by electrochemically active bacteria. The anodic material, which contains a matrix for the attachment of the microorganisms, is usually a limiting factor in power production in an MFC. The anode material and its structure can directly affect bacterial attachment, electron transfer, and substrate oxidation. We have demonstrated that polypyrrole (PPy) coated carbon nanocomposite electrodes are well-suited as an anode in S. oneidensis catalyzed MFC to harvest electricity from bacterial metabolism. The improvement in power generation of the modified anodes may result from the changes of surface functional groups on carbon felt, which enable electrogenic bacteria to grow better on the anodes. |
